I have this new pc since about March, it works fine except that sometimes my raid 0+1 array (4x250Gb Maxtor disks) becomes degraded.
What happens is this: once in a while (lately quite often, thrice in 5 days) one of the disks "disappears", the pc doesn't recognize it anymore and the array gets degraded. Luckily everything keeps on working thanks to redundancy.
I switch off the pc. switch it back on and the disk gets recognized again: then I can use nvidia's mediashield utility to rebuild the array and all is back to normal until it happens again.
Important: the disk is NOT always the same. Sometimes it's one disk, sometimes another.
What could be wrong? I've checked all configuration options in the bios and control panel, it's all good...
Is there a way to convert the array to just 4 separate disks without losing any data and without reinstalling windows?
